ggplot中字体设置的问题

god123

我想用微软雅黑,在ggplot中

theme_grey(base_family="??")

element_text(family="??")

这两项怎么设置

看了以前的一个帖子，还没觉解，但在FONTS下发现有这种字体

可是使用是警告

In grid.Call(L_textBounds, as.graphicsAnnot(x$label), x$x, x$y, :

Windows字体数据库里没有这样的字体系列

怎么设置？

install.packages('Cairo')<br />
require('Cairo')<br />
Cairo(600, 600, file="plot.png", type="png", bg="white")<br />
plot(1:10,1:10,type="n");<br />
text(2,10,"宋体",family="SimSun");<br />
text(2,8,"黑体",family="SimHei");<br />
text(2,6,"楷体",family="KaiTi_GB2312");<br />
text(2,4,"隶书",family="LiSu");<br />
text(2,2,"雅黑",family="MSYH");<br />
text(6,10,"Arial",family="Arial");<br />
text(6,8,"Times New Roman",family="Times New Roman");<br />
text(6,6,"Courier New",family="Courier New");<br />
text(6,4,"Consolas",family="Consolas");<br />
text(6,2,"Symbol",family="Symbol");<br />
dev.off();<br />
getwd()<br />
file.show('plot.png')<br />

</p>

举一反三，以此类推。
